Abstract (en)
[origin: EP0618289A1] A free-flowing granular detergent component or composition having a bulk density of at least 650 g/l which comprises i) at least 35% by weight of anionic surfactant ii) 0.5% to 10% by weight of a chelating agent iii) 0.5% to 30% by weight of a polymer or co-polymer wherein the weight ratio of chelating agent to polymer/co-polymer is from 1:100 to 1:1. A process for making the granular detergent component or composition is also described. It is an essential feature of this process that aqueous solutions of a chelating agent and a polymer or co-polymer are added to a high active surfactant paste.
